Configuring Static Dhcp; Table 4-1 Lan - ZyXEL Communications ZyWALL 5 User Manual

LABEL
Windows Networking (NetBIOS over TCP/IP): NetBIOS (Network Basic Input/Output System) are TCP or UDP
broadcast packets that enable a computer to connect to and communicate with a LAN. For some dial-up
services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls. However it may sometimes be
necessary to allow NetBIOS packets to pass through to the WAN in order to find a computer on the WAN.
Allow between Select this check box to forward NetBIOS packets from the LAN to the WAN and from the
LAN and WAN WAN to the LAN. If your firewall is enabled with the default policy set to block WAN to
LAN traffic, you also need to enable the default WAN to LAN firewall rule that forwards
NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the LAN to the WAN and
from the WAN to the LAN.
Allow between Select this check box to forward NetBIOS packets from the LAN to the DMZ and from the
LAN and DMZ DMZ to the LAN. (Not all ZyWALL models have a DMZ port.) If your firewall is enabled
with the default policy set to block DMZ to LAN traffic, you also need to enable the default
DMZ to LAN firewall rule that forwards NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the LAN to the DMZ and
from the DMZ to the LAN.

Configuring Static DHCP

This table allows you to assign IP addresses on the LAN to specific individual computers based on
their MAC Addresses.
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is
assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02.
To change your ZyWALL's static DHCP settings, click LAN, then the Static DHCP tab. The screen
appears as shown.
